A staring incident involving two drunk men may have prompted an attack that was caught in a video which went viral. The footage shows one man repeatedly stomping on his victim, who was lying motionless on the ground in a mall.

Following the attack, the police said they arrested a 22-year-old Singaporean male suspect last Saturday night. The incident has been classified as voluntarily causing grievous hurt.

In a statement, the police said the incident took place at Golden Mile Complex last Wednesday at about 3am.

The Singapore Civil Defence Force said that a man was taken to Tan Tock Seng Hospital by ambulance. He was conscious and is believed to have suffered severe facial injuries.

The Straits Times understands that the suspect was there for supper with a friend and the altercation erupted outside a first-floor toilet after a staring incident.

The video does not reveal how the 25-year-old male Singaporean victim ended up being floored, but shows a man repeatedly stomping on his head outside a shuttered shop.

The attacker then approaches another man in black, said to be the victim's friend, and punches him.

Bystanders can be heard exclaiming when the attacker returns and stomps on the first man a few more times. The attacker then left in a taxi.

The victim has been discharged from the hospital.

Yesterday afternoon, the suspect was taken back to the scene. Police said he will be charged in court today.
